• Active Link Extraction: Identifies and categorizes all programmed links (External URIs, Internal GoTo/Destinations, Remote Jumps).
• Anchor Text Retrieval: Extracts the visible text corresponding to each link's bounding box.
• Remnant Detection: Scans the document's text layer for unlinked URIs and email addresses that should potentially be converted into active links.
• Structural TOC: Extracts the PDF's internal Table of Contents (bookmarks/outline).

⚠️ Platform Compatibility Note

This tool relies on the PyMuPDF library, which requires specific native dependencies (like MuPDF) that may not be available on all platforms.

Known Incompatibility: This tool is not officially supported and may fail to run on environments like Termux (Android) due to underlying C/C++ library compilation issues with PyMuPDF. It is recommended for use on standard Linux, macOS, or Windows operating systems.

Document Compatibility

While pdflinkcheck uses the robust PyMuPDF library, not all PDF files can be processed successfully. This tool is designed primarily for digitally generated (vector-based) PDFs.

Processing may fail or yield incomplete results for:

• Scanned PDFs (images of text) that lack an accessible text layer.
• Encrypted or Password-Protected documents.
• Malformed or non-standard PDF files.
